How far does the primary surface extend beyond the end of the runway?

• A. 200 feet beyond the runway end
• B. 100 feet beyond the runway end
• C. 300 feet beyond the runway end
• D. 500 feet beyond the runway end

Answer: (A)

The primary surface is the protected strip that surrounds the runway and governs obstacle clearance, extending a fixed distance beyond the runway ends to provide a buffer for landing rollouts and initial climbouts. That fixed extension is 200 feet beyond each end of the runway, with the width matching the runway itself and centered on the runway centerline. Distances like 100, 300, or 500 feet do not match this standard extension, so 200 feet beyond the runway end is the correct requirement.
